In extraordinarily general terms, there are 3 main plans used. You must be agile enough to hop between game plans almost instantly as the course of the game unfolds.
The Blockade
This consists of building a 6-thick wall of checkers, or at least as thick as you might achieve, to block in your competitor’s checkers that are located on your 1-point. This is considered to be the most acceptable strategy at the begining of the match. You can assemble the wall anyplace within your 11-point and your two-point and then shuffle it into your home board as the match continues.
The Blitz
This is comprised of locking your home board as quickly as possible while keeping your challenger on the bar. e.g., if your opposer rolls an early two and shifts one checker from your one-point to your 3-point and you then roll a 5-5, you can play six/one 6/1 eight/three eight/three. Your challenger is then in serious dire straits seeing that they have two checkers on the bar and you have locked half your inner board!
The Backgame
This tactic is where you have 2 or higher pieces in your opponent’s inner board. (An anchor spot is a point consisting of at least 2 of your pieces.) It must be used when you are extremely behind as it much improves your chances. The strongest areas for anchor spots are close to your opponent’s smaller points and either on abutting points or with one point separating them. Timing is critical for a powerful backgame: at the end of the day, there’s no point having 2 nice anchors and a complete wall in your own inner board if you are then forced to break apart this right away, while your challenger is getting their checkers home, owing to the fact that you don’t have any other extra pieces to move! In this case, it is more favorable to have pieces on the bar so that you might preserve your position until your challenger gives you a chance to hit, so it may be a good idea to attempt and get your challenger to get them in this case!
